Exception in thread "main" java.lang.NoClassDefFoundError: DiServer <wrong name: ds/DiServer>
提问by Myn
This is one of those terribly embarrassing questions I'm afraid.
恐怕这是非常令人尴尬的问题之一。
I have a program in Eclipse:
我在 Eclipse 中有一个程序：
package ds;
public class DiServer {
public static void main(String[] args) {
int foo = 0;
int bar = 0;
/*bla*/
}
}
Simple right? This works completely fine when run in Eclipse.
简单吧？这在 Eclipse 中运行时完全正常。
I want to run this from command line. I have copied bin Folder, with the ds folder inside it and DiServer.class in ds, and .classpath
我想从命令行运行它。我复制了 bin 文件夹，里面有 ds 文件夹，ds 中有 DiServer.class，还有 .classpath
I have put these into a separate folder, C:\My Documents\DiTest, opened command prompt, gone to C:\My Documents\DiTest\ds\ and typed java DiServer
我已将它们放入一个单独的文件夹 C:\My Documents\DiTest，打开命令提示符，转到 C:\My Documents\DiTest\ds\ 并键入 java DiServer
The error I get is Exception in thread "main" java.lang.NoClassDefFoundError: DiServer <wrong name:ds/DiServer> ... Could not find the main class: DiServer. Program will exit.
我得到的错误是 Exception in thread "main" java.lang.NoClassDefFoundError: DiServer <wrong name:ds/DiServer> ... Could not find the main class: DiServer. Program will exit.
I have tried java -classpath . DiServer, java -classpath ../.. DiServer, moving .classpath to the ds folder, but I can't seem to get round this. I'm 99% sure it's a classpath problem but I can't work out how to fix it.
我试过 java -classpath 。DiServer，java -classpath ../.. DiServer，将 .classpath 移动到 ds 文件夹，但我似乎无法解决这个问题。我 99% 确定这是一个类路径问题，但我不知道如何解决它。
I would greatly appreciate any help as always, and the customary offer of a pint always stands.
我会一如既往地感谢任何帮助，一品脱的习惯报价始终有效。
Thanks very much in advance,
首先十分感谢，

You class full name is ds.DiServer, not DiServer. From C:\My Documents\DiTest:
你班的全名是ds.DiServer，不是DiServer。来自C:\My Documents\DiTest：
java -cp . ds.DiServer
And voilà.
和瞧。
